The density of ethanol, a colorless liquid commonly known as grain alcohol, is 0.798 [tex] \text{g/mL} [/tex]. Calculate the mass of 31.4 [tex] \text{mL} [/tex] of the liquid in grams.

Answer :

Final answer:

The mass of 31.4 mL of ethanol is 25.028 grams.

Explanation:

To calculate the mass of 31.4 mL of ethanol, we can use the formula for density, which is:

[tex]\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \][/tex]

We are given the density of ethanol as 0.798 g/mL, and we want to find the mass (in grams) of 31.4 mL of ethanol. Rearranging the formula to solve for mass, we have:

[tex]\[ \text{Mass} = \text{Density} \times \text{Volume} \][/tex]

Now, we can plug in the values:

[tex]\[ \text{Mass} = 0.798 \, \text{g/mL} \times 31.4 \, \text{mL} = 25.028 \, \text{grams} \][/tex]

So, the mass of 31.4 mL of ethanol is 25.028 grams.
